AutoRun Flash Projector on Mac OSX?

Hi, I’m currently in the process of making a CD that will auto run on both PC and Mac. At the moment it auto runs on PC and with a custom icon which i made. I have read that mac by default does not allow auto run scripts. Is this true? If not is there a way of creating an auto run file for mac or at least change the default .ico icon to my icon, so that it shows up when payed on a mac.
